| Description | The anatase/rutile mixed crystal $TiO_{2}$ was prepared and modified with Ag decoration and $SnO_{2}$ coupling to construct a $Ag@SnO_{2}$/anatase/rutile composite photocatalytic material. The crystal structure, morphology, element valence, optical properties and surface area were characterized, and the effects of Ag decoration and $SnO_{2}$ coupling on the structure and photocatalytic properties of $TiO_{2}$ were studied. Ag decoration and $SnO_{2}$ coupling are beneficial to reduce the recombination of photogenerated electrons and holes. When the two modification are combined, a synergistic effect is produced in suppressing the photogenerated charge recombination, making $Ag@SnO_{2}/TiO_{2}$ exhibits the highest quantum utilization. After 30 min of illumination, the degradation degree of tetracycline hydrochloride (TC) by pure $TiO_{2}$ increased from 63.3% to 83.1% with $Ag@SnO_{2}/TiO_{2}$. |
